Description

Technical Field

[0001] The utility model relates to the technical field of reconstituted tobacco leaf preparation, in particular to a tobacco rod crushing device in a pretreatment process section. Background Art

[0002] Reconstituted tobacco, also known as tobacco flakes or reconstituted tobacco, is a regenerated tobacco product made from tobacco flakes, tobacco dust, and tobacco stems, which are processed and reassembled into continuous sheets. Tobacco factories and redrying plants generate large amounts of tobacco dust and fines during the production process. To facilitate transportation and reduce storage space, continuous tobacco flakes are typically pressed into dense rods with a diameter of 80mm and a length of 50-150mm. Due to their high density and large dimensions, these pressed rods cannot be reused directly and must be broken down into granules or powder before reuse.

[0003] There are two main types of tobacco rod crushing equipment currently in use. One is a hammer mill, which has defects such as crushing, loud noise, severe equipment wear, weak processing capacity, and easy clogging of the screen when processing dense rods with a diameter of 80mm and a length of 50-150mm. The other is a powerful crusher for Chinese medicinal materials described in announcement number CN216631091U. Although this powerful crusher has advantages such as small crushing and low noise compared to the hammer mill, it has problems such as insufficient processing capacity, overflow at the feed port, severe dust, and easy wear of the blades and screen when processing dense rods with a diameter of 80mm and a length of 50-150mm.
